The aerial array and/or unit of coexistence
In some implementations, in order to improve using the aerial array in multiple directions radiation and/or the space of antenna array unit Covering, aerial array or antenna element can be co-located on single platform or plane, such as above-mentioned plate or dielectric substance.
This realization can be used in the portable radio of notebook, tablet PC, hand-held device etc.. The realization can also be used to cover the Fixed Communication Units of multiple radiation directions, television set, Set Top Box, AP, residential gateway etc..

Coexisted by making antenna or aerial array, can save space, while the space for improving radio communication device/system is covered Lid.Different aerial arrays is substantially independent, and in different directions radiation.It is co-located in by making antenna or aerial array In same module or same plate, institute can be reduced using space, and aerial array and unit are adapted to smaller form factor device. This may be particularly useful in the ever-reduced device of size.
Form the conformal shielding of antenna
Generally, antenna can be such as the package outside of transceiver etc in device.Some realizations can be using antenna as laminated material The part of material is placed, and wherein laminated material includes tube core.Other realization could dictate that antenna be integrated into encapsulation in separate Component.
Conformal shielding can be applied to encapsulation as shielding process.Conformal shielding is that one kind is smeared on molded package/sunk Method of the product metallization thin layer to form barrier enclosure.For example, radio transceiver can be used as the tube core in conformal shielding encapsulation To provide.The selective removal of conformal shielding can create a kind of day being integrated into radio transceiver and antenna in same encapsulation Cable architecture.The being immediately adjacent to property and/or the coupling property improved of tube core (such as radio transceiver) and antenna structure in encapsulation Can, because loss is minimized.
As described below, different antenna types can be used the metallization of conformal shielding to remove to create, including " gap ", " gap bugle ", " slot patch " etc..In addition, it is possible to provide different radiation diagrams and radiation direction (that is, broadside directive, end-fire).Pass through Be integrated into the antenna in this encapsulation, be capable of achieving small form factor, its can be used for such as cell phone and other hand-held devices it In the device of class.In addition, various frequencies can be supported, such as WiGig 60GHz frequencies.As described above, higher frequency spectrum often takes into account Compared with miniature antenna and compared with small package.
Fig. 6 A show the schematic diagram of the broadside antenna formed using conformal shielding.(such as transceiving of tube core 600 Device) it is encapsulated in together with conformal shielding in encapsulation 602.The metallization of conformal shielding is selectively removed to create antenna 604. In this example, antenna 604 is paster antenna, and provides broadside directive radiation, as shown in direction arrow 606.
Fig. 6 B show the schematic diagram of the end-on-fire antenna formed using conformal shielding.(such as transceiving of tube core 608 Device) it is encapsulated in together with conformal shielding in encapsulation 610.The metallization of conformal shielding is selectively removed to create antenna 612. In this example, antenna 612 is gap horn antenna, and provides end-fire radiation, as shown in direction arrow 614.
Therefore, outer antenna elements can be avoided, because antenna is a part for the shielding on tube core.Additionally, antenna feed Line may be coupled directly to tube core.
Strengthen the shaping lens of antenna performance
Device and specifically wireless device can be closed using plastics or dielectric substance, to protect intraware, example Such as circuit board.Generally, this component being closed may include antenna as described above, aerial array and antenna array unit.From The radio wave that this kind of antenna, aerial array and antenna array unit are radiated can pass through plastics or dielectric enclosure material at them Bent during material and bent again.Although there may be because of radio wave, increased associated path is lost by material, effectively Aperture keeps identical when material is with or without.
Fig. 7 shows the schematic diagram of the shaping lens for strengthening antenna performance.Wireless device 700 includes shell 702, shell 702 Can be made up of plastics, dielectric substance or other deformable materials, to create shaping lens housing 704.In shell 702 Portion is one or more antenna elements 706, and antenna element 706 has the effective aperture 708 for respective wireless electric wave 710.It is whole Shape lens housing can effectively increase the antenna aperature size as represented by effective aperture 712.This can to it is physically smaller The a greater amount of radio wave of antenna focusing.Beneficial effect may include the increase of effective antenna gain, and improve link budget, Even if the dielectric loss being associated by closed material 702 with radio wave is still present.
This realization may be particularly useful for the device realized WiGig specifications and be operated in 60GHz frequency spectrums.This considers nothing Line electric wave is likely more protrusion by the loss of closed material in of a relatively high frequency (such as 60GHz).Therefore, when calculating link During budget, increasing effective aperture can help overcome by the loss of material.
This mode can be not limited to platform situation, but can also carry out (in where applicable) in encapsulation or die-level, For example the above.It is contemplated that thickness, radio wavelength of material, shell on shell etc..
